Please can anyone help me work out which chip i've got in my Jap wii?

Hi all, anyone
I'm new to this so please bear with me if i make any mistakes. thanks.
I got a Jap wii from china (it was supposed to be a uk wii from Essex, brought it on ebay).
I know it's got a chip in it as I copied wii sports and it worked ok.
My problem is , I am trying to get it to play SMG(super mario galaxy the Uk pal version), it loads into the wii, and shows in the game channel......, but when I click on it it says "super mario galaxy " but then the screen goes black, and the wii locks up. All I can do is switch it off and on at the plug, to get the Wii going again. I saw someone on youtube with the exact same problem and they had a Wii key in there's, and all they had to do was update the Wiikey. I'm not sure it's a Wiikey in there! Does anyone know if any of the other mod chips behave this same way when trying to load Super mario galaxy? My hope is if no other chip acts this way ,I can definatly say it's a Wiikey and sort it. But if it's another chip and I try to update the chip with a Wiikey update will I mess it up completly?
I really do not want to take my Wii apart unless completly nessessary,
can anyone please help me?
Thanxs Merlin

Hi Merlin, Welcome to WiiHacks. Is SMG the only game with this issue? It could be that it was either a bad image, or bad burn or bad media. You might want explore those areas first.

hi jbloggs, thanks for replying,
Yes the "smg" disk is ok, its a legit disk and it plays on a friends Uk pal Wii ok.
All the other games I have got are NSTC american + Jap, from before the nintendo version 3.3j update. I have updated 3.3j from the wifi,although I did first put the Pal version SMG disk in, and I could not tell you if it updated as it was all in japanese. It did look like it was doing something other than trying to read the disk,but I cannot be sure. But other than not playing the Pal SMG it works fine. I play my Jap version Mario karts ect on the Wifi without probs.
It would be great if I could turn my Jap wii into a Uk pal wii, at least I could understant the writing,and I would love to be able to log on the Uk shopping channel , instead of the Japanese shoping channel..... Hopefully someone will work out how to do it .
thanks..... any other ideas you have would be good to hear, I.ll try almost anything to get it to play on my Jap Wii.
Do you recon there is a fair chance it has the Wiikey in it from what I said in my post earlyier?
thanks Merlin

I think you have to force the language to english for it to work on a jap wii

Hi SDub90,
Thanks for your reply, How do I force the language to English on a Jap console? There is no option for language on my console....... Sorry if I'm being a bit slow, I am new to modding my wii ect .
Thanks Merlin

I Really appreciate the input,
Thanks again
Merlin
